A once green fingered Minnesota man is ruing  not reading the labels on the weed killer he bought after it killed all the  grass on his 40,000 square foot lawn.

Turning the previously lush green grass to  dead, arid scrubland, Lake Elmo resident Rob Olson only wanted to get rid of the  weeds from his two and a half acre lawn.

Instead, Olson says three employees at Dege  Garden Centre consulted with him about which weed product to buy and fatefully  he purchased five bottles of the multi-purpose killer at $35 a pop.
